ClickHouse 26.2 ships 25 new features, 43 performance optimizations, and 183 bug fixes. Key highlights include: the text-index and QBit data type (for vector embeddings with runtime precision tuning) graduating to production-ready status; a new input_format_max_block_wait_ms setting enabling time-based block flushing for streaming inserts; ClickStack UI (observability platform) now embedded directly in the ClickHouse binary; performance improvements for RIGHT OUTER and FULL OUTER JOINs via a more efficient parallel hash-join pipeline; faster inserts into tables with minmax indexes through vectorized min/max calculation; and a new add_minmax_index_for_temporal_columns table setting to automatically create minmax indexes on Date/DateTime columns without manual definition.
